Cadmium telluride (CdTe) photovoltaics or also called Cadmium telluride solar cell is a kind of photovoltaic (PV) technology that can produce electricity from sunlight using a thin-film of compound cadmium telluride to absorb and convert sunlight into electricity. AU - Ramos-Ruiz, Adriana. My writings have appeared in The New York Times, Washington Post and Wall Street Journal, Scientific American, Nature Energy,…, Michael Shellenberger, President, Environmental Progress. Perhaps you have the correct course, perhaps you are on the right road, without verified evidence you have nothing! NO, none of you have, without those carefully made and verified measurements giving evidence that your theory is correct, and can be useful in predicting with good accuracy what the weather and climate will do in the future it is not that worthy. In relation to solar panels, the CdTe is safe while encapsulated in the module, but if the panel is damaged and exposed to … TomOMason: Photovoltaic panels never produce a fraction of their investment energy. Cadmium telluride, while considered less dangerous in relation to acute exposure, is toxic if ingested, improperly handled or the dust inhaled. Alternate silicon-based solar panels have similar issues with lead leaching, although cadmium is suggested to be 10 times more hazardous than Lead. https ://www.thunderbolts.info/forum/phpBB3/viewtopic.php?f=10&t=16430, Vortices are the Pressure Relief Valves of the Atmosphere Low demand for scrap and the high cost of employing workers to disassemble the aluminum frames and other components will make it difficult to create a profitable business unless recycling companies can charge several times more than the target set by [Japan’s environment ministry]. Why Do Jet Streams Exist? If so show it — AND STOP SHOUTING ABUSE! However, a new study shows that certain thin-film solar cells currently on the market could leach hazardous amounts of cadmium after disposal (Environ. Cadmium telluride solar cell, also called cadmium telluride photovoltaic or cadmium telluride thin film, a photovoltaic device that produces electricity from light by using a thin film of cadmium telluride (CdTe). PY - 2017/8/15. Field, Reyes Sierra-Alvarez. Indexed on: 05 May '17 Published on: 05 May '17 Published in: Journal of Hazardous Materials. Perhaps you have the correct course, perhaps you are on the right road, without verified evidence you have nothing! From your link I see lots of negativity against current thinking — all well and fine but where is your science? Field Reyes Sierra-Alvarez Those large surface areas, in turn, require an order of magnitude more in materials — whether today’s toxic combination of glass, heavy metals, and rare earth elements, or some new material in the future — than other energy sources. LOL. TomOMason: Consider the following statements: Were these statements made by the right-wing Heritage Foundation? Studies have shown the heavy metals in solar panels — namely lead and cadmium — can leach out of the cells and get into groundwater, as well as affect plants. When coal is compared to solar photovoltaic generation, the latter could save 51,999 American lives per year if solar were to replace coal generation in the U.S. which also produce large amounts of CO2, driving hazardous climate change? Silicon is the same element in sand, and is non-toxic. Y1 - 2017/8/15 IRENA projected that this amount could reach 78 million metric tonnes by 2050. Several leaching technologies were assessed and the extraction of CdTe from samples of PV modules was optimized for maximum efficiency and minimum cost. If you find any evidence that is inconsistent with my model feel free to bring it to my attention. “Leaching from broken panels damaged during natural events — hail storms, tornadoes, hurricanes, earthquakes, etc. Solar cells, wind bird shredders and biofuels are net energy LOSERS.

Common problematic impurities in glass include plastics, lead, cadmium and antimony.”, Researchers with the Electric Power Research Institute (EPRI) undertook a study for U.S. solar-owning utilities to plan for end-of-life and concluded that solar panel “disposal in “regular landfills [is] not recommended in case modules break and toxic materials leach into the soil” and so “disposal is potentially a major issue.”. What Drives The Jet Streams? “Either it becomes economical or it gets mandated. Climate always changes but you are saying that mans tiny contribution drives climate. Good to give this subject proper attention! Is Sustainable Energy Even Possible Globally? They just want them cheap… There, there is lots of land to install a large amount of panels to make up for their low performance. In other words, there are firms that may advertise themselves as “solar panel recyclers” but instead sell panels to a secondary markets in nations with less developed waste disposal systems. “If waste issues are not preemptively addressed,” warns Mulvaney, “the industry risks repeating the disastrous environmental mistakes of the electronics industry.”. All of that waste creates a large quantity of material to track, which in turn requires requires coordinated, overlapping, and different responses at the international, national, state, and local levels. The problem with putting the responsibility for recycling or long-term storage of solar panels on manufacturers, says the insurance actuary Milliman, is that it increases the risk of more financial failures like the kinds that afflicted the solar industry over the last decade. “We estimate there are 100,000 pounds of cadmium contained in the 1.8 million panels,” Sean Fogarty of Concerned Citizens of Fawn Lake stated to Shellenberger. So if recycling is properly conducted, the toxic materials can be recovered and reused. They will rightly note that there are other kinds of electronic waste in the world. http://www.thunderbolts.info/forum/phpBB3/viewtopic.php?f=10&t=16329. You are not a skeptic. Solar panels often contain lead, cadmium, and other toxic chemicals that cannot be removed without breaking apart the entire panel. Don’t bother replying, as I don’t want more abuse from you. The fact that cadmium can be washed out of solar modules by rainwater is increasingly a concern for local environmentalists like the Concerned Citizens of Fawn Lake in Virginia, where a 6,350 acre solar farm to partly power Microsoft data centers is being proposed. But about 70 percent of the modules were actually sent to recycling, and the recycled metals are in new panels today.”. Sci. “The absence of valuable metals/materials produces economic losses,” wrote a team of scientists in the International Journal of Photoenergy in their study of solar panel recycling last year, and “Results are coherent with the literature.”, Chinese and Japanese experts agree. Just How Accurate Are Weather And Climate Measurements? Head Office: 27 Old Gloucester Street, London WC1N 3AX. Industry often prefers to comply with a single national standard rather than multiple different state standards. Perhaps the biggest problem with solar panel waste is that there is so much of it, and that’s not going to change any time soon, for a basic physical reason: sunlight is dilute and diffuse and thus require large collectors to capture and convert the sun’s rays into electricity. The International Renewable Energy Agency (IRENA) in 2016 estimated there was about 250,000 metric tonnes of solar panel waste in the world at the end of that year. 2013, DOI: 10.1021/es402969c ). In the past, communities living near electronic waste dumps in Ghana, Nigeria, Vietnam, Bangladesh, Pakistan, and India have been primary e-waste destinations. Therefore, it is impossible for any vapors | ACN: 632 317 545 | ABN: 41 632 317 545, SOLAR HOTLINE: 1800-EMATTERS (1800 362 883), Tasmania’s New Solar Incentive For Business, Home Solar Power Systems Boost House Value. A 2004 study commissioned by environmental groups, but contested by the US EPA, concluded that coal burning costs 24,000 lives a year in the United States. The last few years have seen growing concern over what happens to solar panels at the end of their life. Solar requires 15x more materials than nuclearEP. [A]ny mechanism that finances the cost of recycling PV modules with current revenues is not sustainable. “Leaching from broken panels damaged during natural events — hail storms, tornadoes, hurricanes, earthquakes, etc. The advantage of this fund over extended producer responsibility is that it would insure that solar panels are safely decommissioned, recycled, or stored over the long-term, even after solar manufacturers go bankrupt.
